ROTARY FEED FOR STENCIL-MAGHINES.

Specification of Letters Patent.

Application filed September 22, 1910.

Patented July 11, 1911. Serial No. 583,185.

To all whom 'it may concern:

Be it known that I, GEORGE REMNSNIDER, a citizen of the United States, residing at Belleville, Illinois, have invented a certain new and useful Rotary Feed for Stencil- Machines, of which the following is such a full, clear, and exact description as will enable any one skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification.

The object of my invention is to rovide a feed adjustment for stencil machines by means of which circular stencils such as are used for marking barrel heads and the like ma be readily and accurately cut.

n the accompanying drawings which illustrate one form of feeding mechanism made in accordance with my invention together with a portion of a stencil machine to which the same is attached, Figure 1 is a vertical central section; Figs. 2 and 3 are enlarged views showing details of construction; Fig. 4 is a top plan view; Fig. 5 is a diagrammatic view and Fig. 6 is a front elevation partly in section. A

Like marks of reference refer to similar parts in the several views in the drawings.

10 represents the stencil cutting machine which need not be shown in detail as it is fully described in another a plication of even date herewith and same orms no part of the present invention except in combination with the feeding mechanism. Projecting forwardly from the stencil machine 10 are a' pair of rails 11 provided on their lower edges with notches 12. Sliding on the rails 11 is a frame 13. This frame 13 is provided with downwardly extending pins 14 carrying a cross bar 15 on which are mounted a pair of rollers 16 adapted to engage with the notches 12 to hold the frame 13 in its dilerent positions nearer to or farther away from the stencil cutting machine 10. The rod 15 is normally held up by means of springs 17 surrounding th pins 14. Carrled some distance above the frame 13 is a cross bar 18 which together with the frame 13 forms a yoke, as best seen in Fig. 6. Arranged between the cross bar 18 and the frame 13 is a rotary member 19 supported by ball bearings 2O as best shown in Fig. 1.

This rotary member 19 is adapted to support the stencil sheet 21 which is clamped thereto by means of a clamping plate 22. The clamping plate 22 is carried on a spindle 23 passing through the center of the sleeve 24, rotatably mounted in the bar 18. The clamping plate 22 is normally held against the member 19 by means of coil springs 25 surrounding pins 26 which enter openings in the clamping plate 22 and are rigidly secured in a gear wheel 27 carried on the lower end of the sleeve 24. The upper end of the spindle 23 is provided with a head 28 by means of which the clamping plate may be raised out of contact with the member 19.

Projecting forwardly from the cross bar 18 is a bracket 29 in which is mounted a spindle 30. On the lower end of this spindle 30 is a gear wheel 31 meshing with the ear wheel 27. Rigidly secured to the spinle 30 directly above the bracket 29 1s a hand-wheel 32 by means of which the said spindle may be rotated. Rigidly secured to the spindle 30, above the hand-wheel 32 is a hollow rotary member 33. Loosely mounted on the spindle 30 within the hollow member 33 is a block 34 carrying a pivoted member 35 held against the inner periphery of the member 33 by means of a spring 36. This pivoted member 35 acts as a friction clutch so that when oscillating motion is imparted to the member 34 an intermittent rotary motion will be imparted to the member 33. The member 34 1s rovided at its upper face with a pair of ugs -37 having openings through which passes a rod 38 which is driven from the operatin means of the stencil machine. The pivote member 35 is provided near its outer end with an upwardly projecting pin 39 by means of which the said member may be held out of contact with the member 33 so as to allow the spindle 30 to be removed in either direction by means of the handwheel 32.

In order to drive the rod 38 from the stencil cutting machine I secure to the spindle 40 an arm 41 shown in detail in Fig. 2. This arm 41 is held on the spindle 40 by means of a set screw 42. It will be understood that the spindle 40 is given a rocking motion by means of the operating handle 43 of the stencil machine. The upper end of the arm 4l engages with the biilu'cated end 44 of an L-shaped member 45 which is slidingly mounted upon the rod 4G earried by the stencil machine l0. 'lhe L- shaped member 45 is provided on its upper face with an opening for receiving the short down-turned end 47 of the rod 38. In order to prevent the tipping ot the L- shaped member 45 on the rod 4G l provide the upper end of the arm 41 with a washer 48 held in place by means of a screw 49, as shown in Fig. 1. In order to move the frame 13 toward and away from the stencil cutting machine, the bracket 29 is provided with a handle 50.

The operation oi" my mechanism is as follows: In order to insert the stencil sheet. 2l the clamping plate 22 is drawn out of contact with the rotary member 19 by means of the head 28. The stencil sheet may then be slipped in position and the head 23 released so that the springs 25 will firmly clamp the stencil sheet 21 between the rotary member 19 and the clamping plate 22. When the stencil cutting mechanism is operated by means of the handle 43 to cut the character in the sheet, the spindle 40 will be rocked so that the arm 41 will impart sliding motion to the l.shaped member 45. This will move the rod 38 as is shown by dotted lines in Fig. 5, thus imparting an oscillating movement to the member 34. By means of the friction clutch 35 which acts substantially in the same manner asa ratchet this will impart a rotary movement to the member 33 and consequently to the spindle 30 on which the said member 33 is rigidly mounted. The rotation of the spindle 30 will be communicated by means of the gears 31 and 27 to the clamping plate 22 so that the stencil sheet 21 will be moved forward in position to cut the next letter. When the frame 13 is moved nearer to the stencil cutting mechanism the rod 38 will slide in the lugs 37 and an equal amount of movement "of Ithe slidin member 45 will move the member 34 t rough a greater angle as is illustrated by the diagram Fig. 5. At the same time the travel at the point 47 will remain uniform. As this point 47 is substantiall directly over the feed of the base of the etters the feed at the base of the letters will be substantially the same when cutting diierent sizes of circles. As will be seen from Fig. 5, the member as Well as the member 34 travels through diiierent arcs when the frame 13 is in its different positions and consequently it is not practical to use a toothed ratchet for the purpose of chan ing the oscillating movement of the mem er 34 into a rotary movement. When it is desired to move the stencil sheet through a greater distance than the normal feed the member 35 may be moved out of contact with the member 33 by means ol the pin 39 and the stencil sheet rotated by means of the hand-wheel 32.
